Algae wrapped in droplets improves efficiency of artificial photosynthesis
In our quest for the most sustainable, most renewable sources of energy, humanity continues to look to nature for inspiration. One of nature’s most efficient energy systems is photosynthesis, which is how plants convert sunlight, water, and carbon dioxide into chemical energy to fuel themselves. Read More...
This crisis alert app provides crucial information to residents of Kabul
As conditions in Kabul continue to worsen due to the Taliban takeover, residents of the Afghan capital have been struggling to get accurate real-time information about what’s happening in the city.

Study: Algae can resurrect tadpole brain cells
Essential organisms such as plants, microalgae, and certain types of bacteria carry out photosynthesis. This key process releases oxygen into the atmosphere for the rest of us dependent species to feed off and carry out respiration. Every cell in every living thing on earth respires and is the Read More...
World record broken for coldest temperature ever recorded
With our current knowledge of how temperature works there is no upper limit, this means materials can keep getting hotter and hotter to no end. This is not the case for lower temperatures, with the coldest being termed absolute zero, at -459.67 degrees Fahrenheit or -273.15 Celsius, but scientists Read More...
Mimicking cancer therapy has potential application in treating malaria
Parasites are organisms that feed off a host and can sometimes be dangerous to humans by causing disease. One of the most impactful to human health is the strain of Plasmodium, the culprit of malaria. This disease is spread through mosquitoes carrying the parasite which brings about a number of Read More...
Hummingbird-like moth has the longest tongue of any insect in the world
When Charles Darwin came across the long-necked Angraecum sesquipedale orchid species (also known as Darwin’s orchid) on the island of Madagascar, he had a curious thought: There must be an insect on the island with a tongue long enough to feed itself on the plant. “Good heavens,” he Read More...
Following shut offs and hurricanes, Puerto Ricans want a solar future
Puerto Ricans pay nearly twice as much for electricity as mainland Americans, yet random shut-offs and natural disasters like Hurricane Maria often leave many without power. In the wake of the hurricane, a social movement called Queremos Sol was born. Meaning “we want sun,” the movement Read More...
Help scientists locate walruses by becoming a walrus detective
The Arctic is under increasing threat due to climate change, and so is the biodiversity that it supports. That’s why the World Wildlife Fund for Nature and the British Antarctic Survey have decided to collaborate with space tech company Maxar Technologies to initiate the “Walrus from Space” Read More...
California opens its first solar-powered composting facility

The effort is part of new state regulation (SB 1383) which aims to divert 75 percent of organic waste from landfills below 2014 levels by 2025. In response to Read More...
This bandage quickly identifies the severity of a burn
We recently wrote about a bandage design that indicates potential infection. Now, there’s another smart bandage design in the works. This one, literally called SMART, aims to help first responders evaluate and treat severe burns more effectively. Designed by U.S. Army and Massachusetts General Read More...
